God says those people who claim to be Christians but who support and practice wickedness are lying.
1 Corinthians 6:8-10
King James Version
8 Nay, ye do wrong, and defraud, and that your brethren.
9 Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,
10 Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God.
